The invention provides a hair growing cap.

In the embodiment of the present invention, as shown in fig. 1 and 2, the hair growth cap 10 includes a housing 100, a cap-shaped circuit board 200, and a plurality of laser light sources 300.

The housing 100 is in the shape of a cap for enclosing the head of a user.

The cap-shaped circuit board 200 has a shape matching the shape of the inner wall of the case 100. The cap-shaped circuit board 200 is provided in the case 100.

A plurality of laser light sources 300 are spaced apart on the inner wall of the cap circuit board 200.

In this embodiment, the hair growth cap 10 further includes a functional film 400. The functional film 400 covers the plurality of laser light sources 300, and the functional film 400 and the housing 100 form a closed protection cavity, so that the cap-shaped circuit board 200 is limited in the protection cavity, and the waterproof and dustproof purposes are achieved.

In this embodiment, the hair growth cap 10 further includes a closure member 500. The edge seals 500 are provided at the edge of the case 100, the edge of the cap circuit board 200, and the edge of the functional film 400. Specifically, in the present embodiment, the edge sealing member 500 is ring-shaped, the cross section of the edge sealing member 500 is U-shaped, and the edge of the sealing housing 100 and the edge of the cap-shaped circuit board 200 are both inserted into the edge sealing member 500.

In the present embodiment, as shown in fig. 3 and 4, in order to facilitate the assembly of hair growth cap 10, two bendable build circuit boards 600 are used to build cap circuit board 200.

In the present embodiment, the build-up circuit board 600 includes a circuit board body 600a, and the plurality of laser light sources 300 are disposed on the circuit board body 600 a. The circuit board body 600a includes a mating edge 602 and a circumferential edge 604. The abutting edge 604 corresponds to the abutting edge 602 of the other circuit board body 600a, the circumferential edge 604 corresponds to the edge of the opening end of the casing 100, and two ends of the circumferential edge 604 are respectively connected to two ends of the abutting edge 602.

The circumferential edge 604 is formed with a cut 606, the cut 606 being V-shaped. The shear opening 606 includes a first edge 6062 and a second edge 6064, the first edge 6062 and the second edge 6064 establishing a first shear angle α. The first shearing angle alpha is 31 deg. -41 deg. when the circuit board body 600a does not build the cap-shaped

circuit board

200, and 0 deg. -2 deg. when the circuit board body 600a builds the cap-shaped circuit board 200.

Due to process limitations of circuit boards, the circuit boards are usually flat after leaving the factory. The flat-plate-shaped flexible circuit board (flexible circuit board) which can be bent is directly placed into the cap-shaped shell 100, so that the cap-shaped flexible circuit board matched with the inner wall of the shell 100 is difficult to form, poor in effect (prone to wrinkles and unevenness), and inconvenient to efficiently assemble the hair growing cap 10 in a high quality mode.

Two circuit board bodies 600a are provided, two half-hat circuit boards can be constructed by the two circuit board bodies 600a, and the two half-hat circuit boards can be constructed to form the hat circuit board 200. And the difficulty of forming the half cap-shaped circuit board matched with the inner wall of the housing 100 is less than that of forming the cap-shaped circuit board matched with the inner wall of the housing 100, and the effect is better, which is convenient for assembling the hair growing cap 10 with high efficiency and high quality. Furthermore, the cutout 606 formed on the circumferential edge 604 facilitates the formation of a half-hat circuit board matching the inner wall of the housing 100, further reducing the assembly difficulty, and providing a better assembly effect, thereby facilitating the assembly of the hair growth cap 10 with high efficiency and high quality.

And when the cap-shaped circuit board 200 is not constructed on the circuit board body 600a, the first shearing angle alpha is 31-41 degrees, and when the cap-shaped circuit board 200 is constructed on the circuit board body 600a, the first shearing angle alpha is 0-2 degrees, so that the half cap-shaped circuit board matched with the inner wall of the shell 100 is more favorably formed, the assembly difficulty is further reduced, the assembly effect is better, and the hair-growing cap 10 can be more conveniently assembled with high efficiency and high quality.

In this embodiment, there are two cutouts 606, and the two cutouts 606 correspond to two ends of the abutting edge 602, respectively, that is, the two cutouts 606 are arranged at intervals along the extending direction of the circumferential edge 604. The number of the cutouts 606 is too small to reduce the difficulty of forming the half-cap circuit board to be matched with the inner wall of the housing 100, and the number of the cutouts 606 is too large to increase the difficulty of pre-forming the circuit board body 600a outside the housing 100, so that the circuit board body 600a is constructed as the half-cap circuit board outside the housing 100. The provision of two cutouts 606 allows for both of these aspects.

In the present embodiment, the two second edges 6064 are located between the two first edges 6062, and the two second edges 6064 are close to a connection line of the end points of the other circuit board body 600a and the two first edges 6062 (dashed line b in the figure) divide the circuit board body 600a into two parts, i.e., a first part 610 and a second part 620, respectively, where the first part 610 includes the abutting edge 602.

In the present embodiment, the intersection of the first edge 6062 and the second edge 6064 is a through hole 6066.

In the present embodiment, the area of the first portion 610 is larger than the area of the second portion 620. In this manner, it is more convenient to construct the circuit board 600 into a half-hat circuit board matching with the inner wall of the housing 100. Specifically, in the present embodiment, the area of the first portion 610 is 160cm²-250cm²And the area of the second portion 620 is 60cm²-120cm²。

In some embodiments, the first shear angle α is 34 ° -35 °, and the area of the first portion 610 is 165cm²-175cm²And the area of the second portion 620 is 70cm²-80cm²The hair growth cap 10 is now a small hair growth cap 10. specifically, in this embodiment, the perimeter of the open end of the shell 100 of the small hair growth cap 10 is 58-59 centimeters. more specifically, in this embodiment, the first cut angle α is 34.6 °, and the area of the first portion 610 is 170cm²And the second portion 620 has an area of 76.5cm²The circumference of the open end of the case 100 of the small-sized hair growing cap 10 is 58.3 cm.

In some embodiments, the firstA shear angle α of 39-40 deg., and the area of the first part 610 is 193cm²-203cm²The area of the second part is 95cm²-105cm²The hair growth cap 10 is now a medium hair cap 10. specifically, in this embodiment, the perimeter of the open end of the shell 100 of the medium hair cap 10 is 62.4-63.4 centimeters. more specifically, in this embodiment, the first cutting angle α is 39.5 °, and the area of the first section 610 is 198.7cm²The area of the second part is 100cm²And the circumference of the open end of the case 100 of the medium hair growing cap 10 is 62.9 cm.

In some embodiments, first shears α have a cut angle of 39.4 ° -40.4 °, and first portion 610 has an area of 229cm²-239cm²And the area of the second portion 620 is 101cm²-111cm²At this time, the hair growth cap 10 is a large hair growth cap 10. specifically, in the present embodiment, the circumference of the open end of the housing 100 of the large hair growth cap 10 is 64.4-65.4 cm. more specifically, in the present embodiment, the first scissors α have a cutting angle of 39.9 °, and the area of the first portion 610 is 234.6cm²And the second portion 620 has an area of 106.1cm²The circumference of the open end of the shell 100 of the large hair growing cap 10 is 64.9 cm.

In the above-mentioned small, medium and large-sized hair growing caps 10, the first cutting angle α of the medium-sized hair growing cap 10 is larger than the first cutting angle α of the small-sized hair growing cap 10, and the first cutting angle α of the large-sized hair growing cap 10 is substantially the same as the first cutting angle α of the medium-sized hair growing cap 10, that is, in the above-mentioned small, medium and large-sized hair growing cap 10, the first cutting angle α is first increased and then is substantially maintained. The larger the first shearing angle α is, the smaller the area of the circuit board body 600a is, in order to avoid the influence of the first shearing angle α on the area of the circuit board body 600a, after the area of the circuit board body 600a reaches the area requirement of the medium hair growing cap 10, the area of the circuit board body 600a is increased again to form the large hair growing cap 10, and meanwhile, the first shearing angle α is not increased any more greatly, so that the area requirement of the large hair growing cap 10 can be met by the area of the circuit board body 600 a. Therefore, the first shearing angle α is set to 41 ° or less.

In the present embodiment, the build-up circuit board 600 further includes the overlapping portions 600b, and the number of the overlapping portions 600b is the same as the number of the cutouts 606 and is arranged in one-to-one correspondence. Each overlapping portion 600b is disposed within a cutout 606 and is connected to a first edge 6062. The lap 600b includes a lap edge 608 distal from the first edge 6062, the lap edge 608 and the second edge 6064 establishing a second shear angle β. The second shearing angle beta is 5 deg. -25 deg. when the circuit board body 600a does not build the cap-shaped circuit board 200, and the overlapping portion 608 overlaps the second portion 620 when the circuit board body 600a builds the cap-shaped circuit board 200. The arrangement of the overlapping portion 600b and the second shearing angle β is not only beneficial to the circuit board body 600a to form a half-hat circuit board matching with the inner wall of the casing 100, but also has a positioning function when the circuit board body 600a is constructed outside the casing 100 into a half-hat circuit board.

In the present embodiment, the color of the surface of the land 600b is different from the color of the surface of the circuit board body 600 a. Thus, the positioning is more facilitated.

In some embodiments, the first shear angle α is 34 ° -35 °, and the second shear angle β is 6.8 ° -7.8 °. At this time, the hair growing cap 10 is a small size hair growing cap 10.

In this embodiment, the build circuit board 600 further includes an alignment portion 600c, the alignment portion 600c is disposed at an end of the alignment edge 602, and a width of the alignment portion 600c gradually increases in a direction from another end of the alignment edge 602 to the end where the alignment portion 602 is located. The aligning portion 600c may facilitate determination of the front-rear direction of the build circuit board 600 with respect to the case 100.

In this embodiment, two abutting edges 602 of the cap circuit board 200 are each disposed adjacent to the left and right demarcations of the user's head. That is, the two build circuit boards 600 are the left build circuit board and the right build circuit board, respectively.
